Fast Subtrajectory Similarity Search in Road Networks under Weighted Edit Distance Constraints
Satoshi Koide, Chuan Xiao, Yoshiharu Ishikawa
In this paper, we address a similarity search problem for spatial trajectories in road networks. In particular, we focus on the subtrajectory similarity search problem, which invol…
Consistent and Flexible Selectivity Estimation for High-Dimensional Data
Yaoshu Wang, Chuan Xiao, Jianbin Qin +5
Selectivity estimation aims at estimating the number of database objects that satisfy a selection criterion. Answering this problem accurately and efficiently is essential to many…
Monotonic Cardinality Estimation of Similarity Selection: A Deep Learning Approach
Yaoshu Wang, Chuan Xiao, Jianbin Qin +4
Due to the outstanding capability of capturing underlying data distributions, deep learning techniques have been recently utilized for a series of traditional database problems. In…
Pigeonring: A Principle for Faster Thresholded Similarity Search
Jianbin Qin, Chuan Xiao
The pigeonhole principle states that if items are contained in boxes, then at least one box has no more than items. It is utilized to solve many data management pro…
